Castilleja and Pedicularis are confirmed as telial hosts for white pine blister rust in whitebark pine ecosystems of Oregon and Washington

Creator:: Mulvey, Robin L.
Abstract:: The primary objective of this research was to determine if native species within the genera Castilleja and Pedicularis are naturally infected by white pine blister rust (Cronartium ribicola) in whitebark pine ecosystems of the Oregon and Washington Cascade Range. Secondary objectives were to monitor the phenology of aecial and telial...

West Eugene Native Wetland Restoration Research Project: Seed Dormancy, Germination, and Establishment

Creator:: Wilson, Mark V., Ingersoll, Cheryl A., and Clark, Deborah Louise, 1950-
Abstract:: Seed size, abundance, viability, dormancy, and germination requirements strongly influence plant establishment and therefore are important considerations in restoration of native vegetation. These characteristics provide criteria for selection of suitable species, development of collection and pretreatment methods, and determination of seeding densities. The first set of objectives of this study...

Synthesis and assembly of Fucus zygote cell walls with an emphasis on alignate and fucans

Creator:: Doubet, Scott
Abstract:: Fucus distichus L. Powell zygotes were used to investigate cell wall synthesis and development and to construct a model of cell wall structure. Alginate synthesis was investigated. Zygotes were cultured in seawater containing ¹⁴C-bicarbonate. Alginate represented 12%, 37%, and 1.7% of the label recovered from whole zygotes, wall, and cytoplasm,...
